Abstract (en)

[origin: EP3115825A1] The observation image capturing part provided to the tip end of the cable of the internal observation device is made to smoothly approach the portion to be observed. For inserting into a pipe bore 41 a cable 2 of an internal observation device 1, the cable 2 is pushed into the pipe bore 41 to force an observation image capturing part 21 provided proximate a tip end of the cable to approach a portion to be observed 70 when performing internal observation of the pipe bore 41 of a pipelike structure 40 with the internal observation device 1. A guide tube 10 having an outside diameter substantially equal to an internal diameter of the pipe bore 41 to a degree that the guide tube 10 can be inserted in the pipe bore 41, and having an internal diameter substantially equal to an outside diameter of the cable 2 to a degree that the cable 2 can be inserted therein, is inserted into the pipe bore 41 that reaches the portion to be observed 70 and the cable 2 is inserted into a tube interior of the guide tube 10 from an outside of the pipe bore. There may be provided a curved part 12 proximate a tip end of the guide tube 10, the curved part 12 being configured to deflect a direction in which the tip end of the cable 2 that is inserted in a tube interior of the guide tube 10 is directed.
